Why don't you use a solar-powered laptop?

I don't mean a shitty laptop with built-in solar panels for hipsters to buy, but I mean a good laptop (like a ThinkPad or MacBook) with an external solar array. You can even build your own to match the power requirements of your laptop.
>>
because I don't go outside and I'd rather have a solar powered air conditioner
>>
>>43293300
Look at all that power inneficiency
>solar to 12v to 120v to 19v
Most power would've lost as heat in that setup.
>>
>using laptops outside
>>
Because I've got a laptop that lasts 12 hours on a single charge and it charges fast as fuck.

Guess the laptop, /g/!
>>
>>43293392
I would've said the Air, but I used those a while back and they are slow as fuck because of the shitty ULV i5 even with an SSD...
So I say a Thinkpad!
>>
Actually have wanted to get a solar panel like that for a while now.

Anyone know one that could actually charge a laptop? Or have guides on building one?
>>
I've been running my laptop directly off a solar panel for a while, 20v panel>12v boat battery>20v laptop. Not the best setup but it works, feels good man. Btw it's a thinkpad.
>>
>>43293453
How much did the solar panel cost? Have a link to where you got it?
>>
>>43293392
An ARM powered chromebook?
>>
>>43293408
>>43293491
It's a Macbook Air!
>>
>>43293300
Because consumer solars are still have, like, 15% efficfiency and overpriced as fuck. Oh, and BTW, I don't use laptop outside I prefer using it on a desk.

If I wanted to work long time outside, I'd try to fit a raspberry pi, a kindle and a mechanical keyboard into a case.
>>
>>43294137
>>43294156
even if it was just like a terminal+simple editor.

I am look at the monitors they used to code on.

I just don't think the interests there though.

As said there's some e-ink tablets, but they seem to be Chinese only and locked in to mobile OS.
>>
>>43294178
Go be a fag somewhere else, no one wants your overpriced shitbook.
>>
>>43294201
I'm going to look around and see if I can find one of the screens for sale somewhere else. If I can get a screen and hook it up to something which barely draws any power, like an Arduino or Raspberry Pi, it would work great
>>
>>43294013
I would buy something netbook-sized with eink screen. As log as it is not a fucking tablet, I think it'll have its market.
>>
>>43294197
No, it lives in my garage.

For portability, I use an AC inverter in my truck.

There's been some e-ink attempts by indivduals/small groups.

Buy they always end up in production hell, and always obsolete, overpriced, and too late, like that pandora game console thing.

I'd just use a fucking USB keyboard.

Just contacted the eink company, inquiring about 10-14 inch screens and their prices. They apparently offer them up to 20+ inches! Imagine having a full desktop screen in eink, haha.

Since they likely don't have any major hardware assembler ordering it, I'm afraid it's gonna come up really expansive.

You can actually run native linux software on Kobo ereaders, I've installed full busybox, python and qt without even opening it up.
There are also some models that have Usb OTG, so yay!

Here in Italy there are a couple of houses that use solar panels to live off the grid.
They actually don't live off the grid, they are still connected to the electrical company to sell them electricity they don't use.
>>
>>43294660
By "here in italy there are a couple of houses" i meant "near me there are a couple of houses".
Fucking thinking in Italian.
>>
>>43294660
That's pretty cool, it would be nice to have no electricity bill PLUS actually getting money each year just from living with solar panels.
>>
>>43294660
We're going to reach a point in the future where a majority of homes are solar powered, so much so that they generate enough power for everyone.
And because of the way we're doing things now, the power companies are still going to exist, not producing their own power, and just buying excess power from solar homes and selling it for twice the price to non-solar homes
>>
>>43294723
Also, power companies here literally gift solar panels, or make you pay only the installation.

i used a rooted Nook Touch with a keyboard for a while for IRC. I had a T-nut epoxied to the back that I attached to a camera mount, and I had a chopped up USB cable for backfeeding power so I could have the keyboard connected and charge it at the same time.

In Arizona, the local power company used to have an incentives program for homeowners installing solar power.

So many people used this, and made so much money selling power back to the grid, that the power company had to stop the incentives program and is now charging a monthly fee for new installations that get plugged into the grid.

Yeah, the thing about that is when you get enough solar penetration on the grid it fucks things up during peak solar hours. They have to take power from renewable sources like solar and wind first even if they don't need it and pay out mandated rates to these people so they have to pay to have a surplus of power they can't use. They sometimes end up paying businesses that use a lot of power money to burn as much as possible at peak generation hours.

What really sucks is that peak usages often comes later in the evening when solar power is rapidly falling off. This is where they need the inefficient single cycle gas plants to ramp up production fast enough to keep from having brownouts and the like in the evening.
